Looks like my Dometic fridge decided to quit just before a couple of longer trips we had scheduled but no worries, that's why God made ice chests.
Anyway, checked all of the fuses and breakers including the two fuses in the back section; one on the power board the other inline. The fridge will not cool on AC, gas or DC but does have power to the top panel and the back board. I've read that the problem could be in the upper board or lower board.
Anyone have any tips on how to diagnose which board may be the culprit?
I’m not sure what you mean by the thermal switch… maybe just same thing, different terms, but I’ll mention this in case it helps. We had the same ‘symptoms’ in our Dometic fridge. It turns out that the clip that attaches to the fins inside the fridge section at the back had come off. This is the temperature sensor and if it’s not attached to the fin, the fridge and freezer quits. We thought for sure we needed a new fridge, but sliding the sensor back on the fin fixed our problem. Plugged in the trailer and in a few hours it had cooled down to what was expected. The sensor is not super secure on its own and can easily wiggle off if bumped by fridge contents or towing on a bumpy road!
Hi AnJ. The switch I am referring to is a thermal breaker that pops when the gas heating chamber gets too hot. From what I read on other forums, not many folks no about this rascal because it is hidden behind the heat shield on the back side of the fridge.
Thanks for the reply, though. I've learned more about absorption fridges in the past 24 hours than I ever cared to know.
